The PHP ftp_fget() function downloads a file from the FTP server and saves it into an open local file.

<?php
// connect and login to FTP server
$ftp_server = 'ftp.example.com';

$ftp_conn = ftp_connect($ftp_server) or die('Could not connect to ' . $ftp_server);
$login = ftp_login($ftp_conn, $ftp_username, $ftp_userpass);

// open local file
$local_file = 'local.txt';
$fp = fopen($local_file, 'w');

// download file
if (ftp_fget($ftp_conn, $fp, $server_file, FTP_ASCII, 0)) {
    echo 'File successful downloaded';
}
else {
    echo 'Download failed';
}

// close connection and file handler
ftp_close($ftp_conn);
fclose($fp);
?>

// downloads a file from the FTP server and saves it into an open local file

ftp_exec(ftp_conn, command)ftp_fget(ftp_conn, open_file, server_file, mode, startpos)
